Czechoslovakia Application December 27, 1949, Serial No. 135,106 InCzechoslovakia December 27, 1948 The present invention relates to themanufac- 3 Claims. (Cl. 36-115) ture of footwear and more particularlyto a new method of fastening an upper made of ribbons or leather strapsto the intermediate or inner sole, especially in flexible sandalfootwear.

The prior method of fastening an upper, more particularly of the ribbonor strap type, to the intermediate or inner sole by means of metallicfastening means, such as rivets, nails, wire clasps, was time consuming,fatiguing and unpractical. The bent ends of the fastening elementspinched within the shoe and often damaged the sock or stocking.

All these disadvantages have been removed by the method in accordancewith the present invention which resides in that the ribbons or strapsare prevented by means of cotter pins from being pulled out of the slitsformed in the inner sole and through which the ends of such ribbons orstraps are passed. The cotter pins are driven in the parts of the upper,i e. in the ribbons or straps, in such a way that they remain only onthe outer side of the intermediate or inner sole, without damaging thelatter. Further advantages of the present invention will appear from thefollowing description of an example of carrying out the new method asshown in the accompanying drawing, in which Figure 1 is an overall topview of a sandal mounted on a last;

Figure 2 is a bottom view of the sandal showing the cotter pins whichprevent the strap from being pulled out of the slits formed in theintermediate sole;

Figure 3 shows a T-shaped fastening cotter pin; and

Figure 4 shows a double T-shaped cotter pin.

The manufacture of footwear with the use of cotter pins in accordancewith the present invention is carried out as follows:

An inner sole I which is provided with a series of slits 3 for thepassage of ribbons or leather straps 4 is fixed in a manner known per seon a last 2 and when the upper 9 has been mounted on the last, thequarter part 5 of the upper 9 is fastened to the inner sole. Then theribbons or straps 4 of the upper 9 are threaded through the slits 3 in amanner known per se and their ends 6 and the outer side of the innersole are coated with cement so as to cause the ends 6 of the straps,which have been sufflciently tensioned over the edge of the last 2, toadhere to the inner sole l. Prior to the strap ends I being adhesivelyunited with the inner sole, each of them is secured by means of a cotterpin 1 of T-shape, or of double T-shape for wider ribbons or straps, toprevent the ribbons or straps from being pulled out, the cotter pinsbeing driven in from the outside in such a way that they do not damagethe material of the intermediate sole and cannot be pulled through theslits 3 into the interior of the footwear. Then the bottom filling 8 ofthe known fir-tree shape is adhesively fixed and the manufacture of thefootwear is completed in the usual way by fastening the outer sole andthe shoe heel.

What I claim is:

1. A shoe comprising an upper formed of strap members and an inner solemember having slots extending therethrough adjacent the peripheral edgethereof, the ends of the strap members forming the upper extendingthrough the slots in the inner sole member, and a flat fastener memberhaving a shank passing through each strap end and disposed in contactwith the underside of said insole with the shank extending across theslot to prevent withdrawal of the strap from the slot, the ends of saidstraps being bent inwardly to lie against the underside of the innersole member and overlying the shanks of the fastener members passingtherethrough.

2. A shoe as defined in claim 1 in which the flat fastener members areT-shaped and the shank is driven through the strap ends from thedirection of the periphery of the insole.

3. A shoe as defined in claim 1 in which a bottom filler of a thicknesssubstantially equal to that of the strap ends is applied to theunderside of the inner sole and is provided with cutout portions in theedges thereof receiving the inturned strap ends.
